re: "Guess that answers THAT question."
Kidding aside, I was sad when I heard about the breakup. McCartney (I saw a show of his here recently) is a genuinely nice guy, and was devastated by the death of his first wife. It's been observed that one sign that someone was happily married is that they seek to get married again quickly after the untimely loss of a spouse.
His new wife too, seemed to be a nice person, and I wish it had turned out better.
